FORCE-FEED SEED-SOWER.

SPECIFICATION forming part of Letters Patent No. 321,878, dated `luly 7, 1885.

Application filed February 9l85. (No model.)

.To all whom it may concern:

Be it known that we, HANs AMNDsoN and FREDERICK J. HENnrorrsnN, of Racine, in the county of Racine, and in the State of Wisconsin, have invented certain new and useful Improvements in Force-Feed Seed-Sowers; and we do hereby declare that the following is a full, clear, and exact description thereof.

Our invention relates to seed-sowers, and will be fully described hereinafter.

In the drawings, Figure l isavertical transverse sectionthrough the center of our improved seed-sower. Fig. 2 is a section on line x x, Fig. l. Fig. 3 is avertical section online y y of Fig. 2. Figs. 4 and 5 are details of the distributer, and Fig. 6 is a detail on the line z z of Fig. 3.

A is the upper hopper. B is the lower hopper, and G the distributer. A bar, A', arches from one side to the other of the lower hopper, and is formed with a hub, a, that the upper end ofthe driving-shaft B projects up into and is centered by. This bar A is also formed with a lug,a, that is bored to take the inner end of shaft,b,which latter has two arms, b and b2. A link, c, is suspended from the outer end of arm,b,and from the lower end of this link a gate, B2, is suspended, which gate is designed to cover partly or entirely, as may be desired, an opening,B,in the vertical portion of the lower hopper, B, and thus regulate the flow of the seed or fertilizer to the outer portion of the distributer C. This distributer C is made with a central hub, d, surrounded by a slightly-convex disk, d', from which slightly-curved arms d2 radiate, and these arms are formed with ilanges da, that extend over into the disk and terminate each at a groove, c, breaking joints with slightlycurved iianges e', that radiate from the center of the disk ,and also terminate each at a groove, e, so that when the disk d is in place, as shown in Fig. l, the rim of the lower hopper passes down into the groove e and forms a chamber that incloscs the flanges e. The seed to be sown falls from the upper hopper, and from thence, as the distributor revolves, is carried by centrifugal force out through the opening B3 5o in front of the iianges d3, which distribute it.

It will bc observed that though the flanges e and d3 are on the same plate the flanges e are so disposed that each flange e reaches the exit-opening before its companion flange, d3, so that by the time the latter reaches the opening B3 its cast of seed is ready for it.

The arm bZ of shaft b turns on a quadrant, b4, which is scaled,as shown in Fig. 3, so that the height of the gate B2 may be indicated by the position of the arm b2 on the quadrant.

Ve may provide the lower hopper with any desired number of exits B3 and corresponding gates; and we propose in practice to have more than one, to adapt the machine for sowing different seeds and fertilizers.

Though we have spoken of an upper and lower hopper, we may make the two hoppers in one piece without departing from the spirit of our invention. vWe may putasmaller gate, B4, on the gate B2 to serve for very ne seed.

The disk d isformed of four inclined plates, the highest point of each incline beginning at one flange d3, and its lowest point terminating at the neXt flange d3, and so on all around the disk, and, therefore, as the base-lines of the grooves e must all be in the same horizontal plane, (in order to insure atight joint with the base of the lower hopper, B, all around,) it follows that the said grooves will be interrupted, as shown in Fig. 5, and intersected with raised surfaces on the disk d', whenever the inclined plates of said disk fall below the plane of the base-line of said grooves.-

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. In a seed-sower, a hopper projecting below the iloor ofthe machine, said lower part having an exit-opening for the seed or fertilizer, in combination with a vertically-moving gate suspended by a link from the outer end of an arm on a horizontal shaft mounted within the upper portion of the hopper above the door, said shaft extending outside of the hopper and having another arm turning on a sealed'quadrant on the outside of said hopper, as set forth. Y

2. The hopper having exit-opening,in combination with the distributer having an interior and exteriorv set of' flanges, the flanges in the two sets breaking joints, as described.

3. The distributer having convex plate,
